GoPro Protune - not possible?

Hi,

newbie here. In the past I've used GoPro studio for footage made with my old but trusty GoPro Hero 3+ Black. I've always used the ProTune setting on the camera and in GoPro Studio just a simple click on 'Protune' corrected the flat imported colors into nice vivid colors.

I recently decided to try Davinci Resolve, I still have a lot of GoPro clips (again all Protune) waiting to be turned into a movie but of course I need a way to get those nice vivid colors again.

I read another post here that referred to github.com/xtremestuff/protune-transforms (for some reason I am not allowed to post a URL here) so I installed that and am now trying to get it to work. I have found that if I go to the Color tab in Resolve I can now select a LUT if I right-click the clip's thumbnail, eg : LUT -> Protune -> Native -> GoPro_Protune_Native_P3-D65_Scene_v2. This gives the clips I'm working with the exact look I would like them to have. Unfortunately it comes with a YUGE 'DAVINCI RESOLVE - STUDIO' watermark on the screen.

I've read somewhere on this forum that that's because it's not a LUT but a dctl that only the Studio version supports. This is already confusing for a noob. Indeed I see that the files in the Protune folders all have the .dctl extension instead of the .cube extension I see in the other folders but then WHY are they all called LUT and appear in the LUT menu?

There is no way I'm forking out money for a Studio version at this point. It seems very strange to me that a camera as popular as the GoPro series is seemingly not natively supported in Davinci Resolve, but DJI cameras are (eg LUT -> DJI -> DJI_Phantom4_DLOG2Rec709).

I have also tried to add an ACES Transform to the clip and select an Input Transform like GoPro_Protune_Native_ACES_v2 but that makes the image waaaay to dark.

Surely there has got to be some easy way to work with Protune footage, right?

DCTLs are a paid feature, correct.

I use XtremeStuff's DCTL for my GP11 and am happy with the results. I see they also sell LUTS, that should work on free. I have not used the LUTS. https://xtremestuff.net/

They also have a githup repo, depite folders titled 'lut', I don't see any luts (*.cube) here? Maybe they pulled them when they started selling them?

GoPro published free luts for the 12+, but I haven't seen any for the old models.


Gopro has published the GPLog curve for their new cameras, but no the wide gamut primaries. I suspect this is why BM has not added it to the Resolve CST. GP Flat that older models used is documented;

And it uses Rec709 primaries, so all the documentation needed for a CST to be created would seem to exist. So no clue why the GP 10- were never added to the CST.


'Native' White balance is another black box, I believe, so would be a problem for BM. But, I always found it looked horrible on my GP7 and would recommend you avoid it and instead set a manual WB to something that is close. My understanding is the 'Wide Gamut' in the new models is supposed to provide the advantages of Native but let you set a manual WB. But you don't have Wide Gammut in your GP3.


You can find the lut topic here as well

Ground Control used to have a free LUT, but all the links I find online are broken, maybe they pulled it to sell as well?

You can try installing Shutter Encoder (free) too.... it used to come with a Gopro Protune to rec709 .cube LUT.
